The F18 is a highly flexible, modular subwoofer solution where each F18+ unit with its 4,000W amplifier can power itself, as well as 1, 2, or 3 additional F18-Slave units. In-room extension to below 10Hz is possible in the largest to the smallest of spaces. Slave units can be placed separately from the F18+ unit such as an F18+ in the left front corner, and a connected F18-Slave unit in the front right corner.

The X21 is a large subwoofer using a massive, 21″ woofer and a pair of 6″ diameter flared ports allowing for high efficiency and clean output to fill the largest of rooms or bass appetites. We offer two options for the 21″ driver where our X21AD & X21PD models utilize a 4.5″ voice coil design, and our X21AI & X21Pi models utilize a massive 6″ split voice coil design for even more power handling, greater headroom, and even lower distortion. With the durability and efficiency of this system we are happy to allow users to select their own amplification in offering a passive version of the X21 subwoofer with either driver option while we provide recommended DSP filter settings for optimal performance. We also offer a 1200W ICEpower based amplifier with the X21AD variant and our 4000W amplifier with the X21AI which uses the larger 6″ voice coil woofer. You can find rather extensive measurements of what we call the X21PD here at Data-Bass.

The SubMersive was the first product offered by Seaton Sound in 2006. The first owners were all avid enthusiasts who learned about what Mark Seaton was doing with the SubMersive through the fast growing AVS Forum (link to AVS for a bit of nostalgia). Since then the SubMersive has seen 4 upgrades over the years keeping it a top contender against the best subwoofers available. Even more than a decade later the first pair of SubMersives in the linked AVS thread have been upgraded to our latest version of the SubMersive HP+ available here. The SubMersive successfully demonstrated that it was both possible and desirable to offer low frequency extension to below 10Hz in room and dramatically higher dynamic capabilities. You didn’t have to give up a concert kick drum if you wanted the room to shudder when depth charged on the screen. The SubMersive has evolved into 2 variations and a highly refined subwoofer equally at home in the most impressive home theaters and complimenting exotic music systems.

The SubMersive F2+ is a high power subwoofer solution utilizing a pair of 15″ sealed woofers on the front face of the enclosure. Each F2+ unit with its 4,000W amplifier can power not only its own pair of sealed 15″ woofers, but also and additional SubMersive F2-Slave unit. In-room extension to below 10Hz is possible in the largest to the smallest of spaces. Slave units can be placed separately from the F2+ unit such as one F2+ in the left front corner, and a connected F2-Slave unit in the front right corner, or units can be stacked for greater headroom from the same footprint.
